850 wide visual binaries orbital param.

Based on positional observations and measurements of radial velocities, the orbits of 850 wide visual double stars have been determined. The parameters of the log-normal distributions for the histograms of orbital periods, stellar masses, and semi-major axes in astronomical units have been obtained. The eccentricity histogram for binary stars with orbital periods less than 400 years follows a normal distribution centered at e=0.545+/-0.029. For stars with longer periods, this distribution obeys the law f=2e, with accuracy to errors. The mass-to-luminosity relation for stars with well-determined masses is given by: logL_{sun}=4.33logM{sun}-0.11, where L{sun} and M{sun}_ are the luminosity and mass of the star in units of the solar luminosity and mass, respectively.
